The Iran-Iraq war (1980-1988) was one of a series of crises during an era of upheaval in the Middle East: revolution in Iran, occupation of the U.S. embassy in Tehran by militant students, invasion of the Great Mosque in Mecca by anti-royalist Islamicists, the Soviet Union's occupation of Afghanistan, and internecine fighting among Syrians, Israelis, and Palestinians in Lebanon. The war followed months of rising tension between the Iranian Islamic republic and secular nationalist Iraq. In mid-September 1980 Iraq attacked, in the mistaken belief that Iranian political disarray would guarantee a quick victory.
The international community responded with U.N. Security Council resolutions calling for a ceasefire and for all member states to refrain from actions contributing in any way to the conflict's continuation.
The Soviets, opposing the war, cut off arms exports to Iran and to Iraq, its ally under a 1972 treaty (arms deliveries resumed in 1982). The U.S. had already ended, when the shah fell, previously massive military sales to Iran. In 1980 the U.S. broke off diplomatic relations with Iran because of the Tehran embassy hostage crisis; Iraq had broken off ties with the U.S. during the 1967 Arab-Israeli war.
The U.S. was officially neutral regarding the Iran-Iraq war, and claimed that it armed neither side.
Iran depended on U.S.-origin weapons, however, and sought them from Israel, Europe, Asia, and South America. Iraq started the war with a large Soviet-supplied arsenal, but needed additional weaponry as the conflict wore on.
Initially, Iraq advanced far into Iranian territory, but was driven back within months. By mid-1982, Iraq was on the defensive against Iranian human-wave attacks
. The U.S., having decided that an Iranian victory would not serve its interests, began supporting Iraq: measures already underway to upgrade U.S.-Iraq relations were accelerated, high-level officials exchanged visits, and in February 1982
the State Department removed Iraq from its list of states supporting international terrorism. (It had been included several years earlier because of ties with several Palestinian nationalist groups, not Islamicists sharing the worldview of al-Qaeda. Activism by Iraq's main Shiite Islamicist opposition group, al-Dawa, was a major factor precipitating the war -- stirred by Iran's Islamic revolution, its endeavors included the attempted assassination of Iraqi Foreign Minister Tariq Aziz.)
Prolonging the war was phenomenally expensive. Iraq received massive external financial support from the Gulf states, and assistance through loan programs from the U.S. The White House and State Department pressured the Export-Import Bank to provide Iraq with financing, to enhance its credit standing and enable it to obtain loans from other international financial institutions. The U.S. Agriculture Department provided taxpayer-guaranteed loans for purchases of American commodities, to the satisfaction of U.S. grain exporters.
The U.S. restored formal relations with Iraq in November 1984, but the U.S. had begun, several years earlier, to provide it with intelligence and military support (in secret and contrary to this country's official neutrality) in accordance with policy directives from President Ronald Reagan. These were prepared pursuant to his March 1982 National Security Study Memorandum (NSSM 4-82) asking for a review of U.S. policy toward the Middle East.
By the summer of 1983 Iran had been reporting Iraqi use of using chemical weapons for some time. The Geneva protocol requires that the international community respond to chemical warfare, but a diplomatically isolated Iran received only a muted response to its complaints [Note 1]. It intensified its accusations in October 1983, however, and in November asked for a United Nations Security Council investigation.
The U.S., which followed developments in the Iran-Iraq war with extraordinary intensity, had intelligence confirming Iran's accusations, and describing Iraq's "almost daily" use of chemical weapons, concurrent with its policy review and decision to support Iraq in the war [Document 24]. The intelligence indicated that Iraq used chemical weapons against Iranian forces, and, according to a November 1983 memo, against "Kurdish insurgents" as well [Document 25].
What was the Reagan administration's response? A State Department account indicates that the administration had decided to limit its "efforts against the Iraqi CW program to close monitoring because of our strict neutrality in the Gulf war, the sensitivity of sources, and the low probability of achieving desired results." But the department noted in late November 1983 that "with the essential assistance of foreign firms, Iraq ha[d] become able to deploy and use CW and probably has built up large reserves of CW for further use. Given its desperation to end the war, Iraq may again use lethal or incapacitating CW, particularly if Iran threatens to break through Iraqi lines in a large-scale attack" [Document 25]. The State Department argued that the U.S. needed to respond in some way to maintain the credibility of its official opposition to chemical warfare, and recommended that the National Security Council discuss the issue.
Soon thereafter, Donald Rumsfeld (who had served in various positions in the Nixon and Ford administrations, including as President Ford's defense secretary, and at this time headed the multinational pharmaceutical company G.D. Searle & Co.) was dispatched to the Middle East as a presidential envoy. His December 1983 tour of regional capitals included Baghdad, where he was to establish "direct contact between an envoy of President Reagan and President Saddam Hussein," while emphasizing "his close relationship" with the president [Document 28]. Rumsfeld met with Saddam, and the two discussed regional issues of mutual interest, shared enmity toward Iran and Syria, and the U.S.'s efforts to find alternative routes to transport Iraq's oil; its facilities in the Persian Gulf had been shut down by Iran, and Iran's ally, Syria, had cut off a pipeline that transported Iraqi oil through its territory. Rumsfeld made no reference to chemical weapons, according to detailed notes on the meeting [Document 31].
Rumsfeld returned to Baghdad in late March 1984. By this time, the U.S. had publicly condemned Iraq's chemical weapons use, stating, "The United States has concluded that the available evidence substantiates Iran's charges that Iraq used chemical weapons" [Document 47]. Briefings for Rumsfeld's meetings noted that atmospherics in Iraq had deteriorated since his December visit because of Iraqi military reverses and because "bilateral relations were sharply set back by our March 5 condemnation of Iraq for CW use, despite our repeated warnings that this issue would emerge sooner or later" [Document 48].
Rumsfeld was to discuss with Iraqi officials the Reagan administration's hope that it could obtain Export-Import Bank credits for Iraq, the Aqaba pipeline, and its vigorous efforts to cut off arms exports to Iran.
According to an affidavit prepared by one of Rumsfeld's companions during his Mideast travels, former NSC staff member Howard Teicher, Rumsfeld also conveyed to Iraq an offer from Israel to provide assistance, which was rejected
